Tips For First Time Fence Builders
Updated March 15, 2021
Building a fence can sound simple. The process can be broken down into a rather approachable set of clearly defined steps. However, it is only once you are in it that you see all the complexity. The article that follows attempts to save you some headaches by making you aware of a few potential curveballs you may encounter down the road.
The most back breaking part of building a fence is, by far, setting the posts. Posts should be in the ground no less than three feet. Posts that have gates attached to them should be dug even deeper to ensure gates never shift and stop closing. The posts are the single most important part of the fence. They need to be strong, level and straight.
Heaving is when the fence post slowly pops out of the ground. It is a slow process that usually takes place during a spring melt in colder climates. Over the course of a season a post can move serial inches to the point where it is very noticeable that the fence is no longer level. Heaving, occurs when the ground melts and thaws under the bottom of a post. This is why it is so important that post be set below the frost line. In the coldest regions in North America the frost line is never more than three feet below the surface. In warmer climates the frost line is much shallower.
A line locate is when a utilities company marks the underground electricity, gas and telecommunication lines that run under the surface of your property. In this case the "line" is a pipe or wire. The lines will get marked either with spray paint or flags. It is important to get a line locate because hitting a line while digging fence posts can result in serious injuries or large bills to repair the damage. Line locates are free in most cities.
If your fence posts are no good, the sections you attach to them are worthless. Additionally, digging the kind of narrow and deep hole you need for post requires specialised tools. For these reasons a lot of homeowners hire a professional to set the posts even if they plan to build the rest of the fence.
One thing to keep in mind is that you will need to order more material than you actually require. The reason is because not all the boards the supplier will send you will be usable and, no matter how good you are, you might waste a board on a missed measurement or a missed cut. If you don't over order you might get stuck having to use a board in the fence that is in poor condition. Otherwise you will end up having to make a trip back to the store right as you are trying to finish up your fence. You are better off to order additional material and return any extras you have at the end of the job. All major reno stores accept returns.
